Briefings

NASA Earth Observatory released Black Marble HD imagery comparing nighttime lights in the Florida Panhandle before and after Hurricane Isaias. The storm, which made landfall on October 9, 2026, caused widespread power outages visible as darkened areas along the coast and Route 98 corridor. Recovery began by October 14, with lights returning to pre-storm levels. The study highlights the utility of satellite data for tracking disaster impacts and recovery progress.

Key points

• Hurricane Isaias made landfall near Destin, Florida on October 9, 2026, as a Category 2 hurricane with maximum sustained winds of 105 mph.
• Black Marble HD imagery revealed sharp decreases in nighttime lights along the Florida Panhandle coast and Route 98 corridor, indicating widespread power disruptions.

Context

The Florida Panhandle coast experienced heavy rain and flash flooding during Hurricane Isaias, which became the season's first hurricane in August 2026. Satellite data from the VIIRS instrument on NOAA-20 satellite captured the storm's immediate impacts and subsequent recovery patterns.

Limitations

The study relies on preprocessed Black Marble HD data from the VIIRS instrument, which may have gaps in cloud coverage. Recovery timelines are inferred from image pairs spanning October 11 to October 14, 2026, limiting precise assessment of ongoing disruptions.
